CFS Software Implementation

Gregory Landais and Nicolas Sendrier

Abstract

CFS is the first practical code-based signature scheme. In the present paper, we present the initial scheme and its evolutions, the attacks it had to face and the countermeasures applied. We will show that all things considered the system remains practical and we present a software implementation of the signing primitive. For eighty bits of security our implementation produces a signature in 1.3 seconds on a single core of Intel Xeon W3670 at 3.20 GHz. Moreover the computation is easy to distribute and we can take full profit of multicore processors reducing the signature time to a fraction of second in software.
